JDK – all sub-projects
Building via CLI
To build JDK via the command-line interface (InfraBuild) perform the below actions respectively:
cd ~/sources//jdk8_tl/common/makefiles
make clean jdk NEWBUILD=true &> jdkInfrabuild.log
Configurating and building in Eclipse
Do the same actions as above for Hotspot (See How to build the Hotspot project in Eclipse) and translate names and locations that relate to the OpenJDK project. Import the project from /home/openjdk/sources/jdk8_tl/common/makefiles folder, rename the project to something like 'OpenJDK' instead of the 'makefiles' name given by default. Depending on the build system used, apply the below environment variable and argument list settings (does not require the traditional ALT_ ones anymore - instead they should all be unset).
LANG=C PRODUCT_HOME=/home/openjdk/sources/jdk8_tl/build/linux-x64-normal-server-release/images/j2sdk-image ZIP_DEBUGINFO_FILES=0 When setting up the External Builder setting for the Infrabuild system, you can apply one of the below entries in the arguments list:
images clean images images VERBOSE="-d -p" clean images VERBOSE="-d -p"
Note: Please refer to http://openjdk.java.net/projects/build-infra/guide.htmlhttp://openjdk.java.net/projects/build-infra/guide.html for further details on what the arguments mean in the Infrabuild system.
The rest of the instructions to setup the Hotspot project apply. Build the project via the Project > Build Project option and wait for it to finish. The above results in creation of the j2re and j2sdk images in the /jdk8_tl/build/linux-x64-normal-server-release/images folder (in folders j2re-image and j2sdk-image respectively).
Note: you can jump start the process by using the ready-made projects made available in the Github repo mentioned below. A clean build using the InfraBuild system would take an hour on a VM and under 15 minutes on a native machine - all this subject to various performance factors of a system. The Old build system is slower in this respect.
Build dependencies
The JDK project is a composition a number of sub-projects which depend on other artefacts from the below projects:
corba hotspot jaxp jaxws langtools
The build process involves building the sub-projects and the availability of artefacts from the above projects.
Build messages: logs
- A successful run of the build results in the output of the following log messages:
jdkInfraBuild.log
Build output: artefacts
The general JDK build artefacts are a tree of files and directories as shown below and can be found at ~/sources/jdk8_tl/build/linux-x86_64-normal-server-release/jdk:
